1985 Honda

1985 Honda atc 110 3-wheeler in pretty good shape for its age. I've had it for several years and only take it out in the winter to do donuts with, probably the most fun little donut buggy in the snow ever. Always stored inside, it runs very well starts great in the cold. I really hate to sell it but I bought a honda recon so it hardly even got played with this winter. The tires are like new but for some reason when I start it up once a month the back 2 are always low? I put slime in them and they still leak I think it might be the valve stems. You can see in the picture a small part of the plastic was repaired. I replaced the back brake assembly and put a UNI air filter on it. The only thing that I know is wrong is it slips out of gear sometimes, there is a clutch adjustment I've never fooled with it. It has high/low and seemed to slip worse in high so I always just rode it in low it's fast enough in low. That's all I can think of, please ask any questions. And please look at a map before bidding I am located in the most western part of maryland.
